  <p>Overrides the exception to something other than what was constructed. You <em>almost certainly</em> never
want to use this function. A much better way of overriding the exception returned is to create
a custom no-value policy which lazily synthesises a custom exception object at the point of need.</p>

<p>The only reason that this function exists is because some people have very corner case needs
where a custom no-value policy can&rsquo;t be used, and where move-constructing a new <code>outcome</code> from
an old <code>outcome</code> with the exception state replaced isn&rsquo;t possible (e.g. when the types are
non-copyable and non-moveable).</p>

<p>Unless you are in a situation where no other viable alternative exists, do not use this function.</p>

<p><em>Overridable</em>: Not overridable.</p>

<p><em>Requires</em>: Nothing.</p>

<p><em>Namespace</em>: <code>BOOST_OUTCOME_V2_NAMESPACE::hooks</code></p>

<p><em>Header</em>: <code>&lt;boost/outcome/basic_outcome.hpp&gt;</code></p>
